EMFFormat Class
Members  Example 

ArcGIS.Desktop.Mapping Namespace : EMFFormat Class
Represents an Enhanced Metafile Format (EMF) object that can be used to export a MapView, MapFrame, or a Layout.
Syntax
public class EMFFormat : ExportFormat 
Public Class EMFFormat 
   Inherits ExportFormat
Remarks
EMF files are native Windows graphics files that can contain a mixture of vector and raster data. They are useful for embedding in Windows documents because the vector portions of the EMF can be resized without loss of quality. However, since EMF does not support font embedding and is exclusively a Windows format, it is not commonly used as an interchange format between users.
Example
The following examples demonstrate how to export a Layout, a MapFrame, and a MapView to EMF format.
//This example demonstrates how to export a layout to EMF.

using ArcGIS.Desktop.Mapping;                     //Export formats

public class ExportLayoutToEMFExample

  {
    //Reference a layoutitem in a project by name
    LayoutProjectItem layoutItem = Project.Current.GetItems<LayoutProjectItem>().FirstOrDefault(item => item.Name.Equals(LayoutName));
    if (layoutItem == null)
      return Task.FromResult<Layout>(null);

    //Create EMF format with appropriate settings
    EMFFormat EMF = new EMFFormat();
    EMF.Resolution = 300;
    EMF.OutputFileName = Path;

    return QueuedTask.Run(() =>
    {
            //Export Layout
            Layout lyt = layoutItem.GetLayout(); //Loads and returns the layout associated with a LayoutItem
            if (EMF.ValidateOutputFilePath())
      {
        lyt.Export(EMF);
      }
    });
  }

//This example demonstrates how to export an individual map frame on a layout to EMF.

//This example demonstrates how to export the active mapview to EMF.

//Added references
